Hi, Thanks for writing in. Bone cancer can be of many types. The commonest condition is multiple myeloma and this spreads to involves multiple bones including long bones and back bone. It can also infiltrate blood system. There are many other bone cancers like osteosarcoma, ewing sarcoma, metastasis, bone lymphoma and it is important to know the type of cancer the patient has. If he has myeloma that is causing symptoms, he will most likely to be treated with a combination of chemotherapy and steroids. Which drugs he will get will depend on how the myeloma is affecting his general health. For example, if he has kidney damage, this will affect the choice of treatment that his doctor can use. His doctor may also recommend having a biological therapy such as thalidomide, bortezomib (Velcade) or lenalidomide (Revlimid) alongside the chemotherapy and steroids. Other bone cancer can be treated by chemotherapy, surgery and radiotherapy as per disease type and stage. Please do not worry.
